Louis van Gaal was "amazed" Manchester United lost to Swansea City and praised The Reds' creativity at The Liberty Stadium.

Ander Herrera's first-half opener was cancelled out quickly by Ki Sung-yeung and Jonjo Shelvey's shot deflected off Bafetimbi Gomis to record a first-ever league double for The Swans.

The timing of Gomis' 73rd-minute winner came with United in the ascendant and Van Gaal felt Swansea didn't deserve their win.

"No," he responded bluntly when asked if Swansea were worthy winners. "When you think that they deserved the game you have to write it, eh? "This is always frustrating when you lose and are the dominating team, so I agree that you're disappointment is much bigger because of that, so I agree."

Van Gaal insisted United 'created a chance every two minutes', however they managed just three shots on target - three less than their hosts. Stubborn as ever, Van Gaal reiterated The Reds had 'many chances' and dismissed United lacked creativity. When asked how United had lost the game, he replied: "By not scoring the goals out of so many chances.

"In the first-half I think it was an equal game. I count as many chances Swansea had we had the same, there were two goals, so Swansea one and us one, so that was not a big difference but in the second-half it was a big difference.

"I think Swansea had a chance in the first minute of the second-half and after that we were dominating the game. We have created a chance every two minutes but we were not effective.

"And then one counter, somebody's shot deviated, maybe in an offside position, I don't know, from Gomis, and it was the goal and you are not happy and you are not lucky.

"But nevertheless we dominated the game with 10 men because Robin van Persie could not run anymore because of the injury, so I cannot say anything about my players, only that we played a very good second-half and then the disappointment is much bigger."

Ander Herrera got the opener

Van Gaal declined to single out individuals on an afternoon when Angel di Maria suffered what was arguably the nadir in his United career. The Argentinian was substituted for Juan Mata on 79 minutes, while Wayne Rooney and Robin van Persie were an impotent front two.

Van Gaal admitted he would have to analyse the game to decide which players under-performed. "You have to see the slow motions of the match, then you can see which players were not effective," he said.

"I think also a lot of the chances came because of the hurry, the pace of the action. And sometimes you can control the ball instead of shooting directly, but normally we are very effective so it's amazing we have lost today."

Van Gaal was in a philosophical mood, despite the setback. He welcomed the members of the media with a "Good afternoon" before he answered questions thoughtfully, which indicated he was satisfied with United's performance.

He strode onto the pitch at full-time and applauded United's spirited travelling fans with his dejected players, with Daley Blind and Phil Jones particularly crestfallen.

"Win and loss belongs to sport," he added. "You can win and you can lose. In the 19 games it was against Southampton that we lost and after that you have to pick up everything and then you continue.

"Also against Southampton we were the better team, now again, we were the better team.

"But, for example, against Burnley, we were not the better team, Burnley were the better team. And it's also the benefit of football that the result is always unpredictable and that's also the beauty of football.

"But for today it is very disappointing." United have slipped down to fourth in the Premier League table following Arsenal's win at Crystal Palace, and while it is possible The Reds could drop out of the top four when Southampton host Liverpool tomorrow afternoon, Van Gaal remains relaxed.

"I think every game that Man United plays you have to manage that because this is a top club," he said. "And a player and the manager has to manage it, so it's normal."
